摘要
采用液相共沉淀法制备氢氧化镍/石墨烯(Ni(OH)2/GO)复合材料,通过电池测试系统检测对比Ni(OH)2与GO复合前后材料的电化学性能。测试结果表明,将Ni(OH)2与GO进行复合之后,复合材料的比电容达到141.3F·g-1,循环100次后容量保持率为94.6%,较单一的Ni(OH)2有较大的提高。
The Ni（OH）2/GO was prepared by co-precipitation method and the electrochemical performance was tested by battery test system. The test results showed that the specific capacitances reached 141.3F/g and the specific capacitance retention rate was 94.6%. Compared with the Ni（OH）2, the performances of Ni（OH）2/GO had great improvement.
